ISPConfig Update and SSL

Got an e-mail announcing an update was available (never tried doing an update before, so figured I'd try it out) Is there any way to get it so when it does an update it doesn't ask for a new SSL cert? (Shouldn't it be able to use the last one generated?) Problem is I tell people to ignore the warning for the SSL cert not being official, and some of them tell firefox or whatever browser to always allow, and then firefox won't let them get to the config interface after the new ssl cert is generated, because it doesn't match the one it has cached. I guess the other solution is just to not have the ispconfig interface through ssl, it just would be nice if when upgrading it wouldn't ask about the SSL cert.
